Hi, thanks for the reply.
the delay of half second is acceptable.for me.
But how can i save the picture?

My issue is to use the 4 cameras sequentially, using http://www.arducam.com/multi-camera-adapter-module-raspberry-pi/ as fast as possible and save, later if possible, the 4 still pictures (one for each camera). Could i do it streaming from the cameras to a phone and save the pictures? The best would...

Hi, if i connect 4 cameras (5Mp) and use them sequentially, how long would it take to save the images and store it into sd card?
